Exploring Addition and Subtraction of Matrices

This video tutorial covers the basics of adding and subtracting matrices. It begins with an introduction to matrices and their properties, followed by examples of adding and subtracting both 2x2 and 3x3 matrices. The tutorial emphasizes the importance of matching matrix dimensions for these operations and provides step-by-step calculations for each example.
